Perfectly Decomposed!

This Perfectly Decomposed! activity & project also includes:

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment using three samples to explore what variables alter decomposition times. A class discussion at the end of the week allows everyone to share the variable they studied, the results, and more!
